基于RFID的监狱智能定位系统的设计与实现

摘要

In order to solve the difficult problem of management of prisoners , this paper introduces a location technique based on RSSI measurement implemented on CC 1110 system .The system is composed of the tag , reader, wireless repeater and the server .The tag transmits related information to the reader .The reader receives data from the tag and then sent them to the wireless repeater .The system has the advantages of simple structure , low cost and the strong adaptability .Experiment results show that the system can achieve effective localization .%为解决在押犯人管理困难的问题，该文介绍了一种基于射频识别技术的CC1110 RSSI定位系统。系统主要由腕带标签、读卡器、无线中继和服务器组成。标签主要负责对读卡器发送相关信息，读卡器负责接收标签的数据并转发给无线中继，中继通过以太网把读卡器传送过来的数据发送给服务器，服务器负责对数据的处理、分析并进行相关管理操作。该系统结构简单、硬件成本较低、易部署、适应性较强。实际测试表明，该系统能够用于监狱在押人员的定位，降低非视距误差。
